Document using a link for LogoutView

[Alex Dehnert]

The Django 4.1 release notes mention:

If you want to retain the user experience of an HTML link, you can use a form that is styled to appear as a link:

<form id="logout-form" method="post" action="{% url 'admin:logout' %}">
  {% csrf_token %}
  <button type="submit">{% translate "Log out" %}</button>
</form>

However, the admin:logout view appears to require the the user have admin access (at least, empirically, my user that doesn't gets redirected to /admin/ and then /admin/login/). The plain logout URL name (​https://docs.djangoproject.com/en/5.2/topics/auth/default/#django.contrib.auth.views.LogoutView), which doesn't require this, seems like a better fit.

(Relatedly, this information seems pretty timeless -- should it be included in say the docs for LogoutView, rather than just some increasingly-old release notes? Presumably somebody writing a brand-new Django 5.2 app *also* wants to know how to make a logout link. I spent a bit looking around the docs and don't see it mentioned anywhere -- actually, I was a little surprised that the tutorial doesn't obviously mention extending base templates and provide a sample template with a login link, logout link, etc..)

I also argue in #36576 that admin:logout *should* work for logging out non-admin users, but I contend that using admin:logout *here* is wrong independent of that. If nothing else, it appears that ​`auth.logout` and ​the admin variant can use different templates, and presumably most people following these directions to add a logout link are doing it outside the admin context -- the admin has a logout link provided. That said, it's obviously much worse because of #36576 (I only noticed the discrepancy when I finally went to log out a user without admin access, and that wouldn't have been relevant without #36576).

Thank you for the suggestion. I agree this information is useful and shouldn't be hidden in the 4.1 release notes.

I would suggest something be added to the bottom of the ​LogoutView docs (similar to how the LoginView docs has an example at the bottom). I also think that folks find this confusing came up in a ​conference talk.

I don't think updating the 4.1 release notes adds too much value as this is no longer a supported release and we keep old release notes quite static
